If you’ve ever wondered what crystallized Piña Colada looks like magnified under polarized light, then visit the Molecular Expressions Photo Gallery. Maintained by the National High Magnetic Field Laboratory at Florida State University in Tallahassee, the gallery displays micrographs of a wide range of scientific and everyday objects.

Carnegie Mellon University’s Marek Mihalkovic and Michael Widom use density functional theory to calculate the structure and cohesive energies of more than 1500 intermetallic compounds. Organized around phase diagrams, Mihalkovic and Widom’s Alloy Database is especially rich in quasicrystal and metallic glass-forming compounds.

From the physics laboratory at NIST’s Gaithersburg, Maryland, campus comes Energy Levels of Hydrogen and Deuterium. The online database was created by Svetlana Kotochigova, Peter Mohr, and Barry Taylor. It contains calculated energy levels of both hydrogen and deuterium for principal quantum numbers from 1 to 200 and for all allowed values of orbital and total angular momentum.
